Externalizing storage: created an interface for storage
Externalizing storage: Implemented JsonStore as the first storage implementaiton
Externalizing storage: Cleaned up main code to delegate to the store impl for storage of notes.
Changes:
   - JNV was changed to inject a NotesStore to Notes
   - Notes was changed to use the NotesStore and remove all load/store code.
   - Notes was changed to remove the fromJson() methods and to make setLastModified() public.
test jar and corresponding storage file.
uncommented the line that sets date values set from the file
decided course on jnv_ser, vs _json vs _all
converted JNV.java to an abstract class
Renamed JNV.java to JNVBase.java to reflect that it is now an abstract class
JNV_Json now uses JNVBase; fixed JNVBase typos caused due to the rename.
modified build.sh to do a "clean" build every time.
modified build.sh to use a separate manifest file for json and generate a _json.jar.
All of this in prep for making java serialization the primary storage mechanism.
Working version of java serialization as the default storage.
Changes:
   - Re-created JNV.java as extending JNVBase, but using SerializedStore as its store.
   - Note.java had to be made serializable.
   - This also is SerializedStore's first commit.
Moved Manifest files to subdirs under jar in prep for build.sh using those subdirs to create storage-specific jars
Modified build.sh to build separate jars for serialization and json output.
Checking in the jars and test files from the initial test runs
updated todos status
added tasks for v1.0 and v1.1
Fixed problem where noteContent was not being checked for emptyness correctly. Used equals() instead.
Basic version of switch to table working. It still has the following issues:
  - table values are editable
  - date stored is not yet shown
  - blank rows show up in the table, which i've not been able to figure out.

... but its a working version where last modified is displayed.
Working version of last modified in search results. 2/3 issues fixed.
  - read only table
  - actual dates shown
